POCKET LAM]? FOR HIGH EIGHT POWER.

Application filed March 23, 1922. Serial No. 546,207.

T 0 all whom it may concern.

Be it known that I, VILHELM Bonner, a subject of Prussia, residing at Berlin, Germany, have invented certain new and useful Improvements in aPocket Lamp for High Light Power, of which the following is a specification.

My invention relates to a pocket lamp of the kind in which an illuminating material, such as magnesium, is used as a source of light. It is the object of my invention to provide a device which can be conveniently carried in a pocket and permits of a dangerless use of the lighting device. To produce a very intense light I use an illuminating material which is rolled down to a ribbon of extreme thinness, i. e., a ribbon which is less than 0.0039 inches thick. A special feature of my invention is a case having a discharge nozzle for the illuminating material which is rendered foldab-le so as not to project from said case when folded into inoperative position. It is 0W- ing to this feature that my device may be used as a pocket device. Another feature of my invention resides in the fact that said nozzle may be caused to automatically move into operative position, when the lamp is to be ignited. Other features will be referred to in the following description of an embodiment of my invention, which is illustrated by way of example in the accompanying drawing, in which Figure 1 shows a pocket lamp with its case opened. Fig. 2 is an end view of the device with the case in its closed position, and Fig. 3 a plan view of the Figure 1. i

The lamp case consists of two hinged parts 1 and 2, the hinge 3 of which is provided with the spring 4 that tends to open said case, when a spring 15 fastened by means of rivets 16 is depressed by means of button 17 so far that the pin 18 releases the coil part 2. A coil 5 of a magnesium ribbon 14: is mounted on a pin 6 and retained thereon by means of a split pin 7. Said ribbon passes over a feed roll 8 mounted on a pin 9 and projecting partly through an opening within an end wall of said case 1. In front of the feed roll is mounted on a pin 11 a discharge nozzle 10 which can be folded against a wall 18 within the case part 1 and is retained in its. projected or operative position shown in Figure 1 by means of a spring 12.

Through this nozzle the ribbon let is passed so that its end projects there-from. In accordance with the consumption of the ribbon when burning more of the ribbon is fed by revolving the roll 8 by frictional contact with the thumb of the hand that holds the device while the other hand may be used for igniting the ribbon 14. For the sake of convenience I may accommodate a suitable igniter 21 within a compartment 20 secured in said case 1 by means of a screw 23.

The interior of the cover 2 may be used for storing cigarettes 25 as indicated in Figure 1 in dash-and-dot'ted lines, and for that purpose the case part 2 may be enlarged for the space 24 indicated in Figure 2 in dash-and-dotted lines. Elastic bands 26 fastened on apertured ears 27 may be provided for holding the cigarettes in position.

That I claim is:

1. A pocket lamp, comprising'in combination, a case, a strip of illuminating material arranged within said case, and a discharge nozzle for said strip of illuminating material and arranged on said case, said discharge nozzle being adapted to be folded inside said case.

2. A pocket lamp, comprising in combination, a case adapted to be opened, a continuous strip of illuminating material, a carrier for said strip and arranged within said case, a discharge nozzle on said case and adapted to be folded into inoperative position inside said case, means for feeding said strip through said nozzle and arranged so as to be manipulated from outside of said case, and means for automatically returning said nozzle into operative position.

3. A pocket lamp, comprising in combination, a case having a hinged cover, a continuous strip of illuminating material, a carrier for said strip and arranged within said case, a discharge nozzle on said case said nozzle being adapted to be folded into inoperative position within said case and so arranged relatively to said case. as to be automatically retained in inoperative position by said cover when said cover is closing said case, means for automatically returning said nozzle into operative position when said case is being opened, and means for feeding said strip into said nozzle and arranged so as to be manipulated from outside of said case.

4. A pocket lamp, comprising in combination, a case, a strip of illuminating material arranged Within said case, and a discharge nozzle for said strip of illuminating material and arranged on said case, said discharge nozzle being adapted to be folded inside said case and an igniting device accommodated Within said case, so as to be accessible from outside of said case.

5. A pocket lamp, comprising in combination, a case having a hinged cover, a continuous strip of illuminating material, a carrier for said strip and arranged Within said case, a discharge nozzle on said case said nozzle being adapted to be folded into inoperative position Within said case and so arranged relatively to said case, as to be automatically retained in inoperative position by said cover when said cover is closing said case, means for automatically returning said nozzle into operative position when said case is being opened, and means for feeding said strip into said nozzle and arranged so as. to be manipulated from outside of said case, and an igniting device a0- co-mmodated within said case; so as to be accessible from outside of said case.
